Default 97 civic lx - coolant leak--- no idea

97 civic lx with 145k miles

coolant leak (having to top off once a week or every several hundred miles), losing coolant out of the radiator as well as the reservoir.

at 135k miles, the head gasket, water pump and timing belt were done

i just replaced the radiator cap and reservoir

mechanic did pressure test, said it was a hose clamp and that i am good to go

still losing coolant after 100+ mile drives

no visible leaks


what is happening here

Make sure the plug on the radiator is tight. Also a possibility the seal is broken between the radiator and end tank. I went through 4 radiators when I had my 98 DX. After the second one I should've went with an all aluminum radiator and saved a few bucks.
